Dynamic quick sand filter and integrated deep treatment equipment for sewage

The utility model discloses a dynamic quick sand filter and integrated deep treatment equipment for sewage. The dynamic quick sand filter comprises a tank body, wherein the tank body is internally filled with a sand bed and an air inlet pipe is arranged at the top of the tank body; the air inlet pipe is communicated with a sand washing device arranged in the tank body; the bottom of the sand washing device is communicated with a water inlet pipe; the bottom of the water inlet pipe is connected with a water distributor; the tank body is internally provided with a sand suction pipe penetrating through the water distributor and the water inlet pipe; and an air stripping device is arranged in the height direction of the sand suction pipe. When the filter works, the sewage enters from the water inlet pipe and enters the water distributor; the sewage flows out from the water distributor to enter a sand bed to be filtered; and suspended matters are intercepted by the sand bed and filtered treated water is discharged from the upper part of the tank body. Quartz sand of the suspended matters is intercepted at the bottom and enters the sand washing device from the sand suction pipe through a sand lifting device; the quartz sand is washed and falls into a filtering bed to be continually filtered; and washing water for washing the quartz sand is discharged through a dreg discharging pipe. An air blower and the air inlet pipe are used for providing an air source to the sand lifting device to realize an air stripping function and finish circulated washing of the quartz sand.
